ENZYME entry: EC 2.3.1.279

The enzyme, characterized from the bacterium Mycobacterium
tuberculosis, participates in the biosynthesis of polyacyltrehalose
(PAT), a pentaacylated, trehalose-based glycolipid found in the cell
wall of pathogenic strains.

The enzyme catalyzes two successive activities - it first transfers
an acyl (often palmitoyl) group to position 2, followed by the
transfer of a mycolipenyl group to position 3 (see EC 2.3.1.278).
